1) A Clean Energy Strategy


 The world keeps getting warmer and 

we’re contributing to the problem 

with the devices that are supposed to cool us



Even Existing “Sustainable” Fans are 
bound to end up in landfils 




Bill of materials 
Life Cycle Analysis (LCA): 


Solarpunk: 

 a social, literary, and artistic movement that imagines technology, nature, and humanity in harmony 

Solarpunk is the design philosophy for Solair

Future Strategy:


Why Solarpunk Values are relevant today:  








Why many people don’t adapt Solar Energy:













So, what would real sustainable personal cooling look like?



















Sustainable cooling products exist, but most ask users to spend more, sacrifice convenience, or commit to infrastructure they don't own


Solar adoption fails not because of performance, but because of perceived inconvenience and behavioral friction









Key Insights:


1. People increasingly value energy independence, especially as climate and policy become less stable


2. Sustainable products fail when they demand 
 a behavioral sacrifice 
= convenience is non-negotiable


3. Solar and cooling products are perceived as seasonal, which limits how much people are willing to invest in them

Benchmark Fan vs Solair




   



97% Decrease in CO2e/5 years of use with Solair!




















The stakeholders who benefit from Solair’s design:












communities who are stop mining petrolium for plastic

to the end buyer 

the larger environment and ecosystem 

Making sustainability feel inevitable rather than imposed was the hardest design constraint

If I were to continue this project, I'd prototype the Powerfoyle integration to test whether the energy output works under indoor conditions


Equitable Energy through a shared Product System Service:






Solair  

a personal fan powered entirely by Powerfoyle cells, usable both indoors under ambient light and outdoors in direct sun. It requires no charging cable and no dedicated solar panel; it works wherever you are
